Effectiveness of exercises by telerehabilitation on pain, physical function and quality of life in people with physical disabilities: a systematic review of randomised controlled trials with GRADE recommendations.

OBJECTIVE: Investigate whether exercise-based telerehabilitation improves pain, physical function and quality of life in adults with physical disabilities. DESIGN: Systematic review of randomised controlled trials. DATA SOURCES: Searches were performed in AMED, MEDLINE, CINAHL, SPORTDiscus, Embase, PEDro, Cochrane Library and PsycINFO. ELIGIBILITY CRITERIA: Trials were considered if they evaluated exercise by telerehabilitation. The population included adults with physical disability. Comparisons were control and other interventions. The outcomes were pain, physical function and quality of life. Study selection, data extraction and analysis followed the protocol registered in PROSPERO (CRD42019122824). GRADE determined the strength of evidence. RESULTS: Forty-eight trials were included in the quantitative analysis. When compared with other interventions, there was high-quality evidence that telerehabilitation was not different to other interventions for pain (95% CI: -0.4 to 0.1), physical function (95% CI: -0.2 to 0.2) and quality of life (95% CI: -0.1 to 0.5) at long-term. There was moderate-quality evidence that telerehabilitation was not different to other interventions for physical function (95% CI: -0.1 to 0.5) and quality of life (95% CI: -0.2 to 0.5) at short-term. However, due to the low-quality evidence and the small number of trials comparing exercise protocols offered by telerehabilitation with control groups, it is still not possible to state the efficacy of telerehabilitation on pain, function and quality of life at short-term and long-term. CONCLUSIONS: Exercise by telerehabilitation may be an alternative to treat pain, physical function and quality of life in adults with physical disabilities when compared with other intervention.

Functioning of young patients with cerebral palsy: Rasch analysis of the pediatric evaluation of disability inventory computer adaptive test daily activity and mobility.

BACKGROUND: People with cerebral palsy experience limitations in performing activities of daily living. Rehabilitation practitioners seek valid instruments to measure changes in the performance of those activities. The Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT) is a new tool to assess functioning in children and youth with various health conditions. Its validity needs to be evaluated in a way that is consistent with the theoretical model on which it was based. We aimed to evaluate the fit of daily activity and mobility items and children with CP to the Rasch model and to compare the performance in daily activities and mobility of older children, adolescents, and young adults with CP based on manual function and gross motor function limitations. METHODS: Eighty-three parents of children and youth of 8-20 years old (mean age: 11.6) with different severity levels of cerebral palsy participated in this study. Ninety-one items of the PEDI-CAT Daily Activities and Mobility domains were analyzed through Rasch analysis to evaluate relative item difficulty and participant ability. Participants were described according to the Manual Ability (MACS) (level I: 21.7%; II: 32.5%; III: 24.1%; IV: 7.2% and V: 3.6%) and the Gross Motor Function (GMFCS) (level I: 37.3%; II: 26.5%; III: 6%; IV: 18.1%; and V: 7.2%) classification systems levels. RESULTS: Our data fit the Rasch Model. Parents had difficulty distinguishing some PEDI-CAT response categories. Participants from MACS and GMFCS levels IV and V showed lower ability to perform relatively more difficult items. There was a floor effect in both domains. Only 7.7% of the items presented differential item functioning when individuals with mild MACS and GMFCS levels (I, II) and moderate level (III) and individuals with moderate (III) and severe levels (IV, V) were compared. CONCLUSIONS: PEDI-CAT daily activities and mobility domains are valid to evaluate children, adolescents and youth with CP of different severities, but the addition of items to these domains is recommended in order to address their floor effect.

Family-Centered Early Intervention Program for Brazilian Infants with Congenital Zika Virus Syndrome: A Pilot Study.

Aims: To evaluate the effects of a 16-week program based on Goals-Activity-Motor Enrichment (GAME) principles on infants with congenital Zika virus syndrome (CZS)'s mother report of functional goal achievement, motor and cognitive abilities, home enrichment, and parents' perceptions regarding the service provided. Methods: Quasi-experimental study with infants (n = 32) with CZS and their mothers. Twenty-two infants composed the GAME-based group and 10 were included in the control group. The primary outcome measure was the Canadian Occupational Performance Measure. Secondary outcome measures were the Bayley Scales of Infant and Toddler Development, the Affordances in the Home Environment for Motor Development-Infant Scale, and the Measure of Processes of Care. All measures were performed by blinded assessors. Results: Mothers of infants in the GAME-based group reported significant improvements in their infants' performance on functional priorities (p = 0.0001) and satisfaction with their infants' performance (p = 0.0001), the extent in which services promoted enabling and partnership (p = 0.021), provided general information (p = 0.039), specific information (p = 0.0001), and an enriched home environment (p = 0.0001). Infants in both groups did not improve in motor or cognitive abilities. Conclusions: A family-centered early intervention program based on GAME principles improved mothers' individualized outcomes and enriched infants with CZS's environment. Future studies should elucidate long-term benefits of interventions for this population.

Functional Task Training Combined With Electrical Stimulation Improves Motor Capacity in Children With Unilateral Cerebral Palsy: A Single-Subject Design.

PURPOSE: Reduced propulsive capability can impact negatively on mobility activities of many children with spastic unilateral cerebral palsy (SUCP). This study investigated the effect of a task-oriented training program combined with functional electrical stimulation (FES) on the motor capacity of children with SUCP. METHODS: Single-case A-B design with follow-up. Gross motor function and biomechanical walking data of 4 children with SUCP were measured repeatedly across the baseline, intervention, and follow-up phases. Intervention was a task-oriented training program combined with FES applied on the gastrocnemius. Outcome variables included gait speed, impulsive torque, and ankle/hip power generation ratio. The 2-SD band and celeration line methods compared outcomes among the baseline, intervention, and follow-up periods. RESULTS: One child improved walking speed. All children improved impulsive torque and ankle/hip power ratio of the affected leg. All children improved gross motor function. CONCLUSION: The intervention improved children's propulsive capability and positively influenced their mobility.

Rasch analysis of the participation scale (P-scale): usefulness of the P-scale to a rehabilitation services network.

BACKGROUND: A person's participation is acknowledged as an important outcome of the rehabilitation process. The Participation Scale (P-Scale) is an instrument that was designed to assess the participation of individuals with a health condition or disability. The scale was developed in an effort to better describe the participation of people living in middle-income and low-income countries. The aim of this study was to use Rasch analysis to examine whether the Participation Scale is suitable to assess the perceived ability to take part in participation situations by patients with diverse levels of function. METHODS: The sample was comprised by 302 patients from a public rehabilitation services network. Participants had orthopaedic or neurological health conditions, were at least 18 years old, and completed the Participation Scale. Rasch analysis was conducted using the Winsteps software. RESULTS: The mean age of all participants was 45.5 years (standard deviation = 14.4), 52% were male, 86% had orthopaedic conditions, and 52% had chronic symptoms. Rasch analysis was performed using a dichotomous rating scale, and only one item showed misfit. Dimensionality analysis supported the existence of only one Rasch dimension. The person separation index was 1.51, and the item separation index was 6.38. Items N2 and N14 showed Differential Item Functioning between men and women. Items N6 and N12 showed Differential Item Functioning between acute and chronic conditions. The item difficulty range was -1.78 to 2.09 logits, while the sample ability range was -2.41 to 4.61 logits. CONCLUSIONS: The P-Scale was found to be useful as a screening tool for participation problems reported by patients in a rehabilitation context, despite some issues that should be addressed to further improve the scale.

Upper limb performance and the structuring of joint movement in teenagers with cerebral palsy: the reciprocal role of task demands and action capabilities.

Individuals with unilateral cerebral palsy (CP) demonstrate reduced performance in upper limb tasks compared to typically developing (TD) peers. We examined whether task conditions modify differences between teenagers with and without CP during a reciprocal aiming task. Twenty teenagers (nine CP and 11 TD) moved a pointer between two targets as fast as possible without missing a target. Task conditions were manipulated by changing the targets' size, by modifying the inertial properties of the pointer and by varying the upper limb used to perform the task (preferred/non-affected and non-preferred/affected upper limbs). While compared to TD peers, CP teenagers exhibited lower performance (longer movement times). Such differences were attenuated when the task was performed with the preferred upper limb and when accuracy requirements were less stringent. CP teenagers were not differentially affected by the pointer inertia manipulation. Task conditions not only affected performance but also joint kinematics. CP teenagers revealed less movement at the elbow and more movement at the shoulder when performing the task with their less skilled upper limb. However, both CP and TD teenagers demonstrated a larger contribution of trunk movement when facing more challenging task conditions. The overall pattern of results indicated that the joint kinematics employed by individuals with unilateral CP constituted adaptive responses to task requirements. Thus, the explanation of the effects of unilateral CP on upper limb behavior needs to go beyond a context-indifferent manifestation of the brain injury to include the interaction between task demands and action capabilities.

Predictive Factors of Household Task Participation in Brazilian Children and Adolescents.

Home environment is an important setting for child participation. This study investigated the participation of Brazilian children and adolescents in household self-care (SC) and family-care (FC) tasks. Interviews were conducted with 109 caregivers of children and adolescents ages 6 to 14 years residing in Belo Horizonte (Brazil). Multiple regression models revealed that a greater number of FC tasks were performed by children and adolescents (R2 = .23) from families who did not have a housekeeper and those in which the mothers did not work outside of the home; children and adolescents from this subgroup also received less assistance from the caregivers (R2 = .21) and showed greater independence in task performance (R2 = .20). On average, Brazilian children and adolescents participate in about half of the SC and 25% the FC household tasks. Factors related to family structure and child's age were associated with task performance, caregiver assistance, and child and adolescent independence in household tasks.

App-based telerehabilitation program for older adults on waiting list for physiotherapy after hospital discharge: a feasibility pragmatic randomized trial.

BACKGROUND: Inactivity while waiting for outpatient physiotherapy worsens the physical deconditioning of older adults after hospital discharge. Exercise programs can minimize the progression of deconditioning. In developing countries, telerehabilitation for older adults on the waiting list is still in the early stages. This study aimed to evaluate the feasibility of the study procedures of a telerehabilitation program for older adults waiting for outpatient physiotherapy after hospital discharge. METHODS: This pragmatic randomized controlled trial recruited older adults (≥ 60 years) with several clinical diagnoses on the waiting list for outpatient physiotherapy in the Brazilian public health system after hospital discharge. The telerehabilitation group (n = 17) received a personalized program of multicomponent remote exercises using a smartphone app. The control group (n = 17) followed the usual waiting list. We assessed recruitment and dropout rates, safety, adherence, and satisfaction. The preliminary effects were verified on clinical outcomes. RESULTS: We recruited 5.6 older adults monthly; dropouts were 12%. No serious adverse events were associated with the telerehabilitation program. The weekly adherence was 2.85 (1.43) days, and in 63.3% of the weeks the participants were enrolled, they performed the exercise program at least twice a week. Participants rated the telerehabilitation program as 9.71 (0.21), and the safety of remote exercises without professional supervision as 8.6 (2.2) on a 0-10 scale. CONCLUSIONS: The telerehabilitation program using a smartphone app was safe and presented high participants' satisfaction and adequate adherence, recruitment, and dropout rates. Therefore, the definitive study can be conducted with few modifications. TRIAL REGISTRATION: Brazilian Registry of Clinical Trials (ReBEC), RBR-9243v7.

Geographic intelligence to investigate community participation: a scoping review.

PURPOSE: To understand the applicability and unique contributions of global positioning system (GPS) and geographic information system (GIS) technologies to investigate individuals' participation in the community. METHODS: A scoping review was conducted to summarize studies that employed GPS and/or GIS to assess community participation. Systematic literature searches were performed using nine electronic databases, up to April 2022. Two independent reviewers screened studies for eligibility and extracted data from the selected studies. RESULTS: The searches retrieved 628 articles, of which 36 met the inclusion criteria. In 31 studies, a GPS unit or GPS-enabled device monitored the community mobility of individuals with different health conditions. Tracking periods varied from five hours to 30 consecutive days. The spatiotemporal parameters obtained from satellite-based data provided information about individuals' presence in the community. Most studies combined GPS with other measuring tools (self-report diaries/questionnaires, qualitative interviews) to capture a broader description of community participation. CONCLUSIONS: GPS and GIS are viable approaches for advancing research as they provide unique information about community participation not easily captured by other methods. The combination of available methods comprehensively address the physical and social dimensions of this construct.IMPLICATIONS FOR REHABILITATIONGlobal positioning system (GPS) and geographic information system (GIS) technology allows direct and real-time quantification of patterns of individuals' community mobility.The geographic area where individuals participate in daily living activities complements information from self-report diaries/questionnaires.Combining GPS technology with self-report diaries/questionnaires allows a broader description of individuals' community participation, addressing respectively both its physical and social dimensions.Knowledge of individuals' access to and involvement in community locations/situations may help therapists design interventions to improve community participation.

Parental priorities in the home care of preterm and full term newborns.

BACKGROUND: The initial weeks after hospital discharge is a period of adaptation when parents assume great responsibility for the care of their child. Preterm birth may impact their demands of care. AIMS: To compare parental priorities in the care of preterm and full-term newborns in the first two months after hospital discharge and to identify changes in priorities over time. METHODS: Parents of 22 full-term and 19 preterm infants were followed for two months after hospital discharge, with three timepoint evaluations of the parental priorities. They reported on infant care demands in a semi-structured interview. RESULTS: Despite prematurity, demands were similar between groups. Within-group changes occurred over time. Priorities related to bathing and caring for the navel showed significant reduction (p < 0.01); demands related to children's health care increased in the groups (p < 0.01). Feeding and sleep priorities were reduced in the full-term group (p < 0.02). Children's adaptation to routine increased significantly in the preterm group (p = 0.04). CONCLUSION: Knowledge of parents' priorities in caring for preterm or full-term newborns at home helps health care teams develop appropriate support strategies and improve specialized assistance to the families.

Lower limb inter-joint coordination patterns are associated with walking experience in toddlers according to limb and stance periods.

Walking experience is crucial for inter-joint coordination during gait acquisition. Toddlers show asymmetrical lower limb function during early locomotion for transferring body weight (regulatory limb) and steering the direction of walking (impulse limb). This study aimed to investigate the association between coordination patterns and walking experience, and between coordination variability and walking experience according to healthy toddlers' lower limb function and stance periods. Typically developing toddlers (n = 22; 17.27 ± 3.13 months) were distributed into two groups: up to (LWE) and greater than (GWE) three months of walking experience. The lower limbs were classified as regulatory or impulse limb and analyzed during the onset (SO), mid (MS), and late (LS) stance intervals. Hip-ankle, knee-ankle, and hip-knee coupling angle (CA) and its variability (CAV) were assessed. A relationship was found between inter-joint coordination pattern and groups, which was distinct according to stance period and lower limb function: (a) hip-ankle CA: at SO for both limbs, MS for the regulatory limb, and LS for the impulse limb; (b) knee-ankle CA: at SO for both limbs and MS for the regulatory limb; (c) hip-knee CA: at SO for both limbs, at MS for the regulatory limb, and LS for the impulse limb. These findings were linked to differences observed in distal joints between groups, mainly at the ankle during stance onset. The CAV was negatively associated with walking experience only in the regulatory limb in the following variables: hip-ankle at MS, knee-ankle at SO, and hip-knee at LS. Findings showed different functional roles of the lower limbs in dealing with the demands of balance and propulsion during early walking.

Cross-country validity of the Alberta Infant Motor Scale using a Brazilian sample.

BACKGROUND: Previous validity studies of the Alberta Infant Motor Scale (AIMS), using raw scores and percentile curves for group comparisons, showed that infants in Brazil achieved gross motor milestones at later ages. Validity of the AIMS norms were later reassessed using a logistic regression model that placed the AIMS items on an age scale. OBJECTIVES: Our study examined the validity of the AIMS norms for Brazilian infants using the recommended method for calculating and comparing item locations. METHODS: Data from 732 Brazilian infants (2009-11), 3 days to 18 months old, were compared to the AIMS normative sample (n=2202). Logistic regression placed the AIMS items of both samples on age scales representing the age at which 50% of infants passed an item and compared the two datasets. Pearson correlation coefficient tested the association across samples. RESULTS: 47 of the 58 AIMS items met the criterion for stable regression to calculate item locations of the Brazilian dataset. Based on the age when 50% of the infants passed a criterion, most of the items from the Brazilian sample (n=28) differed by two weeks or less compared to the Canadian normative sample. CONCLUSION: The sequence and age for the emergence of AIMS items were similar between the Brazilian and Canadian samples. Canadian norms are appropriate for clinical decisions and research with Brazilian infants.

Telerehabilitation program for older adults on a waiting list for physical therapy after hospital discharge: study protocol for a pragmatic randomized trial protocol.

BACKGROUND: Delays in starting physical therapy after hospital discharge worsen deconditioning in older adults. Intervening quickly can minimize the negative effects of deconditioning. Telerehabilitation is a strategy that increases access to rehabilitation, improves clinical outcomes, and reduces costs. This paper presents the protocol for a pragmatic clinical trial that aims to determine the effectiveness and cost-effectiveness of a multi-component intervention offered by telerehabilitation for discharged older adults awaiting physical therapy for any specific medical condition. METHODS: This is a pragmatic randomized controlled clinical trial with two groups: telerehabilitation and control. Participants (n=230) will be recruited among individuals discharged from hospitals who are in the public healthcare system physical therapy waiting lists. The telerehabilitation group will receive a smartphone app with a personalized program (based on individual's functional ability) of resistance, balance, and daily activity training exercises. The intervention will be implemented at the individuals' homes. This group will be monitored weekly by phone and monthly through a face-to-face meeting until they start physical therapy. The control group will adhere to the public healthcare system's usual flow and will be monitored weekly by telephone until they start physical therapy. The primary outcome will be a physical function (Timed Up and Go and 30-s Chair Stand Test). The measurements will take place in baseline, start, and discharge of outpatient physical therapy. The economic evaluations will be performed from the perspective of society and the Brazilian public healthcare system. DISCUSSION: The study will produce evidence on the effectiveness and cost-effectiveness of multi-component telerehabilitation intervention for discharged older adult patients awaiting physical therapy, providing input that can aid the implementation of similar proposals in other patient groups.

Determinants of Time to Care for Children and Adolescents With Disabilities.

Time use studies uncover the organization of daily routine of families of children with disabilities. The objective of this study is to identify determinants of time spent caring for children/adolescents with cerebral palsy (CP), autism spectrum disorder (ASD), and typical development (TD). Participants were caregivers of children/adolescents with/without disability. Structural equation modeling tested a proposed model of time spent in child care. The variables in the model were as follows: questionnaire (families' socioeconomic status [SES]), children's functioning (The Pediatric Evaluation of Disability Inventory-Computer Adaptive Test [PEDI-CAT]); hours of care (daily diaries), number of adaptations used, and help with child care (parents' report). Distinct variable combinations explained 78% of the variation in the time to care (TD model), followed by 42% (ASD) and 29% (CP). Adaptations indirectly affected time to care through its effect on functioning (CP); family's SES affected functioning through its effect on adaptation use (ASD). In conclusion, knowledge of factors affecting caregivers' time spent on children's care help occupational therapists implement family-centered strategies.

Adapted version of constraint-induced movement therapy promotes functioning in children with cerebral palsy: a randomized controlled trial.

OBJECTIVE: To evaluate the effects of constraint-induced movement therapy on the use of the affected arm and on daily functioning in children with hemiplegic cerebral palsy. DESIGN: A single-blinded randomized clinical trial. SUBJECTS: Sixteen children with cerebral palsy randomized to intervention (n = 8, 4 males, 4 females, mean age 5 years and 6 months) and control groups (n = 8, 4 males, 4 females, mean age 6 years and 7 months). INTERVENTIONS: Non-affected arm of intervention group was restricted for 10 hours/ day and the affected arm intensively trained for 3 hours/day for two weeks. The intervention protocol included one week of bimanual functional training following constraint therapy. The control group maintained usual rehabilitation throughout the intervention period. MAIN MEASURES: Pediatric Evaluation of Disability Inventory (self-care domain) and an adapted version of the Jebsen-Taylor test were administered before and after intervention, and at one month follow-up. General linear models tested differences in gain scores and the number needed to treat estimated relative effectiveness of intervention protocol for functional skills and independence in self-care. RESULTS: Results are reported for 15 children who completed assessments and intervention. Higher gains were observed in the intervention group for functional skills and independence post intervention (d(functional skills) = 1.61, P =0.0134; d(independence)=1.37; P =0.0001) and follow-up (d(functional skills) = 2.08, P =0.004; d(independence) = 0.85; P =0.0016). No group difference in manual dexterity gains was observed. Low indices of number needed to treat (1.75 and 2.33) illustrate clinical relevance of intervention. CONCLUSIONS: The protocol associating constraint-induced movement therapy and bimanual functional training was effective in promoting daily living functioning among children with cerebral palsy.

Combining balance-training interventions with other active interventions may enhance effects on postural control in children and adolescents with cerebral palsy: a systematic review and meta-analysis.

BACKGROUND: Improvement of postural control in children and adolescents with cerebral palsy is a primary goal in child rehabilitation. OBJECTIVE: A systematic review investigated whether combining balance-training interventions with other active interventions enhances the effects of the active intervention alone on postural control of children and adolescents with cerebral palsy. METHODS: Searches were performed in MEDLINE, PEDro, CINAHL, Cochrane and EMBASE databases without date or language restrictions. Randomized controlled trials investigating the combination of balance-training interventions with other active interventions on the postural control of children and adolescents with cerebral palsy were included. Two independent reviewers screened studies, extracted data, and assessed methodological quality of included studies. Meta-analysis was conducted, and quality of the evidence followed the GRADE methodology. Pooled data were presented using standardized mean difference and 95% confidence interval. RESULTS: Seven studies involving 194 participants were included in this review. A large additional effect on postural control was found when balance-training interventions were combined with Neurodevelopmental Treatment at short-term (standardized mean difference of 1.3; 95% confidence interval 0.5, 2.0, p=0.001). The quality of the evidence was very low due to publication bias, imprecision and inconsistency. CONCLUSION: Combining balance-training interventions with other active interventions may enhance effects on postural control of this population at short-term. As the estimated effect had only very low quality of evidence to support it, larger studies with low risk of bias are needed.

Interest of children with unilateral spastic cerebral palsy in bimanual daily activities.

Background: Many bimanual activities are challenging for children with unilateral spastic cerebral palsy (USCP).Aims: To investigate hand use by children with USCP in daily activities of their interest.Material e methods: Sample included twenty children with USCP, aged 8 to 14 years old. Participants identified bimanual activities of their interest and no interest. Children's performance on these activities were videotaped. Videos were coded according to the affected extremity's forms and effectiveness of use, caregiver provision and types of assistance, and child's satisfaction. The relative proportions of each parameter were compared using the signed-rank test, considering the time spent in activities of interest and no interest.Results: We analyzed 116 activities. We found effects of interest in children's satisfaction (p = 0.003) and on the type of assistance (p = 0.03). Specifically, children demonstrated longer periods of satisfaction performing activities of their interest and caregiver physical assistance was provided for longer periods of time in activities of no interest. There were no effects on the other parameters.Conclusions: A model that illustrates the impact of a child's interest on the performance of daily bimanual activities is presented, grounded in our results and in the literature.

Identification of gait events in children with spastic cerebral palsy: comparison between the force plate and algorithms.

OBJECTIVE: To compare the gait event identification of five algorithms recommended in the literature with those provided by force plate (gold standard) in children with unilateral or bilateral spastic cerebral palsy (SCP). METHODS: This was a cross-sectional study of the gait of three girls and four boys with a mean age of 8.6±4.7 years. Four children had unilateral SCP with an equinus gait pattern, and the remaining three children exhibited bilateral SCP with a slide/drag gait pattern. Kinematic and kinetic gait data were collected during barefoot walking at a comfortable speed. From a total of 202 steps, the detection of 202 foot-strike (FS) and 194 toe-off (TO) events by each algorithm was compared with the detection of these same events by the force plate. The error between the events detected by the algorithms and those detected by the force plate was determined in milliseconds. Repeated measures ANOVA was used to compare the errors among the algorithms. RESULTS: The algorithm reported by Ghoussayni et al. showed the best performance in all situations, except for the identification of FS events on the unaffected side in children with unilateral SCP. For these events, the algorithms reported by Desailly et al. and Zeni et al. showed the best performance. CONCLUSION: Ghoussayni et al.'s algorithm can be used to detect gait events in children with SCP when a force plate is not available.

Children with congenital Zika syndrome: symptoms, comorbidities and gross motor development at 24 months of age.

BACKGROUND: Children with congenital Zika syndrome (CZS) maintain severe motor impairments at the end of the first year of life. Presence of certain symptoms and comorbidities increase these children's vulnerability. AIMS: To evaluate gross motor function of a group of Brazilian children with CZS at 24 months of age and to investigate the association between the presence of CZS symptoms and comorbidities with gross motor development. METHODS AND PROCEDURES: Fifty children with CZS participated in the study. Information was collected from medical charts, and gross motor development was evaluated by the Gross Motor Function Measure (GMFM)-88. GMFM-88 scores were compared among comorbid groups. Three subgroups of children were identified by cluster analysis, based on information from head circumference at birth, symptoms, comorbidities and gross motor function. OUTCOMES AND RESULTS: Significant associations (p < 0.001) were observed between number of comorbidities/symptoms and dimensions A (r = -0.57) and B (r = -0.58) of the GMFM-88. Children were grouped into 3 clusters, with different gross motor skills. Children with epilepsy and dysphagia composed the cluster with smaller median scores for dimensions A and B of the GMFM-88. CONCLUSIONS AND IMPLICATIONS: The presence of CZS symptoms and comorbidities compromise the gross motor repertoire of children with CZS at 24 months.
